White House officials are distancing themselves from a campaign Donald Trump's former chief strategist, Steve Bannon, has mounted to defend the president from impeachment, after tensions flared again this weekend between Bannon and Jared Kushner.

Kushner and his wife, Ivanka Trump, who are both senior advisers to the president, were angered by revelations about Bannon's interactions with special counsel Robert Mueller that emerged on Saturday, three people familiar with the matter said.

Buzzfeed News obtained previously undisclosed records from Mueller's investigation including an email Bannon wrote in July 2017 alleging that Kushner and Ivanka Trump vacationed with a Russian billionaire during the president's election campaign. A person familiar with the matter denied that they were accompanied by any Russians.
